Overcharges lithium batteries Review by Tim
Easy set up, high-quality components, works

Two major things:
A. No BMS control, not compatible with Lithium batteries.
This controller over-charged one of my LIFEPO4 cells to 4.7 volts because it could not: A: Be controlled by my Orion BMS and B: Could not detect a rapid rise in voltage near the end of the charge cycle. This $4,000 battery pack must be protected from overcharging by re-designing this controller to:
1. Charge enable input, controlled by a BMS (Battery Management System)
2. Lithium battery charging algorithm may detect a rapid rise in voltage, signifying a full lithium battery pack.

B. Poor UI on MSView software.
The 1990's is calling and they want MSView back. Please revamp the UI to include:
1. Graphical representation of battery voltage, current, watts, etc... over time.
2. Automatic displays, instead of requiring five clicks to display array power, voltage, current, watt-hours, etc...
3. Easier display of watt-hours. I was unable to get watt-hours to display. (Posted on August 7, 2017)
